otl' position by a spring 2%. The magnet 98 is connected in circuit with one side of the battery through a conductor 26, switch contacts 2? andQS and conductor 29 and the other side of the battery by a conductor St). The closing 01 the switch "formed by the contacts LI? and 28 serves to energize the magnet 23, causing it to attract its arn'iature and produce a movement ot the lever 18 and with it the movement of any one of the trace reds whose hook 16 is in a position to be engaged by the bar 17. The inoreiuent 0'? each hook 1.6 to a position to be engaged by the bar 17 is produced by an clcctroniagnet 31. connected in circuit. with one side of the battery by a conductor 32 in circuit with the conductor and connected in circuit with the other side of the battery by a eoiuluctor contacts 3i and 2-35 adapted to be bridged by a switch member 36 and a coiuhietor 37 connected to the cimductor 26. A contact 38 connected to a conductor 39 in circuit with a relay electromagnet ll) which is connected by a conductor ll to the conductor 30. An armature 4:2 is normally held in its ofi position by the spring contact 28, but when the circuit is closed through the magnet it) by bridging any one ot the sets of the contacts 37 and 238 the armature is attracted and the contact 28 is moved by said armature into contact with the contact 27. There are as many sets ot contacts 3 and 38 and bridging contac s 3t) as there are trace rods for tori ing combinations as hereinafter deseribeih the contacts 3;) being in circuit with a common conductor 37 and the contacts 38 being in circuit with a common conductor 3. The contacts 234: have separate conductors 33 leading to the magnets 31. Each bridging contact is here shown forming part of a push button awitcln the buttons for the ditterent trace rods being shown in Fig. l and designated 1. 2, a and O. In this construction when one oi} the push buttons is pressed in the bridging piece carried thereby first bridges the contacts and 35 nd thereafter the contacts 35 and 3S. \Vhen the contacts 3%: and are bridged the magnet 31 for one of the trace rods controlled by this button is energized and the hook 1G is raised to a position to be operatively engaged by the bar 17 which is subsequently moved when the magnet 23 is energized on the e gagcinent of contact 28 with contact eiifected by the energization of the 11mg net 40 when the contacts and 38 are bridged. It will therefore be apparent that while the bar 17 is moved when any one of the push buttons is actuated, selective actuation oi": the trace bars is accomplished by the use of the magnets 31 and the hooks 16.

The stop keys 43 are mounted on a shaft 44 and are adapted to be held in either oli or on. position by a looped spring 45 interposed between a screw 46 on the frame or the organ and an arm 47 on the key. Each stop key forms a lever pivotally supported intermediate its ends and the rear end of each lever has a rod or link 48 connected thereto for vertical movement by the swin ing of the stop key. This rod. 48 connects with a link 4-9. The link 49 operatively connects a pair of transversely extending setter rods 50 and 51, respectively, positioned above and below the trace rods.

The setter rods are each journalled at one end in the organ frame and have yoke portions 50 and 51 and cranks 50 and 51, respectively. The yoke portion 50 of the rod 50 extends downwardly to a position a short distance above the tops of the trace rods and the yoke portion 51 ot' the rod 51 extends upwardly to position a short distance below the bottoms of the trace rods. The cranks 50" and 51 are connected to the link 49 and the movement of this link swings the yoke portion 50 ot the rod 50 in anarc above the trace rods in a direction opposite to that in which it swings the yoke portion 51 in an are below the trace rods.

These setter rods 50 and 51 are adapted to cooperate with triggers 52 on the trace rods. Each trigger 52 is pivotally mounted intermediate its ends upon a pivot. on one of the trace rods and has fingers 54 and 55 oliset from the pivot point and adapted to al ternately project beyond the trace rod. A spring 56 is pivotaily mounted at one end on a pin 57 in line with the pivot 53 and pivotally connected at its other end to an arm ['8 on the trigger. The spring 56 acts to hold the trigger in either of two posiions, that is when the arm 58 moves past the line oi centers between the pivot 53 and pin 57 the spring exerts a pressure on the trigger to swing and hold either the finger 54 projected above the trace rod or the finger 55 projected below the trace rod. The fingers 54 and have inwardly extending projections 54 and 55 which act as stops engageable with the trace rod to limit the swinging movement of the trigger.

lVhen the trigger 52isinit-s on position as shown in Fig. 4 where the end of finger 54 projects above the trace rod, it is in a position to engage with or be engaged by the yoke portion 50 of the upper setter rod 50. When the trigger 52 is in its of? position. where the end of finger 55 projects below the trace rod, it is in a position to engage with or be engaged by the yoke portions 51 of the lower setter rod, some of the triggers being shown in this position in Fig, 2.

The triggers on any trace rod may be set in their on or off position when such trace rod is moved from its normal position to its setting position. As previously pointed out, a spring 10 holds each trace rod in normal position and the rod is moved to a setting or on position by pressing the push button which controls the hook 16 of this rod so that the magnet 23 and the linkage connected therewith may move this rod against the action of the spring 10. Assuming that the off position of the stop keys is the dotted line position shown in Fig. 3, then when any one of the trace rods is moved to a setting position, that combination of. steps which it is desired to have come on simultaneously during the playing of the selection is effected by the operator pressing down on the desired stops, moving them to the full line or on position shown in Fig. lVhen any one of the stop keys is thus moved down those trig ers on the trace rods in their settingpositions which are off are moved to on because the downward movement of any one stop key causes the rod 51 associated with this key to move the trigger 52 from its off to its on position. Similarly the upward inm'ement of any one of the stop keys causes the rod 50 associated with this key to move the trigger 52 from its on to its off position. Thus the operator sets the triggers so that during the playing when he moves the trace rod to its on position those triggers 52 which have been for on will engage the rods 50 and cause said rods to swing and through the links 48 and 4-9 brings on the desired stop keys and those triggers 5: set for ofl will engage the rods 51 and. through the mechanism above described more the desired stop keys to off while the push button controlling this trace rod is pushed in. l urtherniore, when the push button has been pressed in, bringing on a previously combination of stop keys, it the player desires to temporarily bring on one or more additional step keys, or release one or more or" the stop keys from operative to OH position this may be done manually by the player without eilecting the previously set combination, allowing it to be brought on in its original arrangement when its controlling button is again pressed in, since the movement of any one of the stop keys when the trace rod is not in a set or on position does not effect the position of the trig gers on this rod. lVhen a combination of stop keys controlled by any other push button is to be etl'ected the pressing in of such button will eliminate from or add to the previously operative combination of stop keys according to the selection set, and by the use of a plurality of triggers and a plurality cl trace rods a great number of combinations or arrangen'ients of the stop keys may be produced. One of the trace rods, as for instance that controlled by the button 0, may have its triggers set so as to cancel or bring all the stop keys to off position after any combination of stop keys has been put on, as will be readily understood by those skilled in this art.

The stop keys are originally arranged in groups, and in Figure 1 I have shown the mechanism in one 01" such groups for bringing all the stop keys of such group to on or to oil position. This is accomplished by providing bars 56 and 56 with arms mounted for rocking on a shaft 57 having a switch member 36 which in each instance is adapted to cooperate with contacts 8 1 and 38, one set of said contacts being shown in connection with the bar 56 Either one or these bars 56 or 56 with the switch member 36 provides, when depressed downward, the same operative contact for operating a trace rod as in the ma ner previously described in connection with the contacts 36, 35, 34 and 38; by the use of these bars the trace rod which the bar controls may have all the triggers set to oil? position and the trace rod which the bar 56 controls may have all the triggers set to on position whereby he depression of the bar 56 will act to move any of the stop keys in the group which are on to off position and the bar 56 move any of the stop keys in such group which are. not on to an on position.

I desire it to be understood that this iinvention is not to be limited to any speciticform or arrangement of parts except in so "far as such limitations are specified in the claims.
